7. If the voltage readings match those listed in Tables 5.1 and 5.2 and one or more keys do not
function, replace the upper PCA.
8. If the voltage readings in Table 5.1 are incorrect, disconnect the keypad cable from the key
pad connector and repeat the voltage measurements in Table 5.1. If the voltage readings
are now correct, replace the display housing (keypad). If the voltage readings are still
incorrect, replace the upper PCA.
9. Set the circuit breaker in the “off” position.
10. If necessary, carefully re-connect the keypad cable to the keypad connector.
